Safe Wood Finishes for Food Prep: A Guide for Grocery Store Options
When it comes to choosing a food-safe wood finish for your kitchen, you might be wondering which oils are best to use from your local grocery store. This guide will help you select and apply the right oil safely and effectively to ensure your wooden surfaces remain safe for food preparation.
Commonly Used Oils for Food Safety
There are several grocery store oils that can be used as food-safe wood finishes, each with unique properties and applications:
Mineral Oil
Mineral Oil is a popular choice for cutting boards and other kitchen utensils. It is considered food-safe and helps protect wood from moisture, preventing it from drying out or cracking. To apply mineral oil, simply clean the wood surface thoroughly, apply the oil generously, let it soak in for a few hours, then wipe off any excess. For best results, you can sand and reapply mineral oil whenever the board starts to look dried out or scratched.
Coconut Oil
Coconut Oil is another food-safe oil that offers antimicrobial properties, making it a great choice for wood surfaces. While it provides a nice finish, it may need to be reapplied regularly due to its tendency to go rancid over time. To use coconut oil, apply it to the wood surface and let it sit for several hours before wiping off any excess. Reapplication is recommended every few months.
Olive Oil
Olive Oil, while food-safe, can turn rancid and may not provide the best long-lasting finish. However, it can be a good option for a quick finish or a shorter term application. Apply the oil to the wood surface and let it sit for several hours, then wipe off any excess. Regular reapplication is necessary for best results.
Walnut Oil
Walnut Oil is another food-safe oil that dries to a hard finish, making it suitable for various wood items. Note that if you or anyone using the item has nut allergies, be cautious. Apply walnut oil to the wood surface, allowing it to dry fully. Sand and reapply as needed to maintain the finish. It is also eco-friendly and naturally mold-resistant.
Beeswax
Though not an oil, beeswax can be combined with any of the above oils to create a durable food-safe finish. Beeswax can be melted at a low temperature and mixed with the oil or used as a top coat. This combination can provide additional protection and shine.
Traditional Corn and Soybean Oils
Corn and vegetable oils are often used for wood surfaces such as chopping boards and butchers blocks because they do not taint food. These oils will require several applications to achieve the desired finish. Apply a single coat and allow it to dry completely. Repeat the process up to six to seven times to ensure the board is well protected. Regular reapplication is necessary to maintain the finish and prevent the wood from drying out.
Linseed Oil: A Controlled Application
Linseed/flaxseed oil is a traditional choice for wood finishes. However, it is crucial to use food-grade flaxseed oil, as linseed oil sold as a wood finish is not suitable for food contact surfaces. Allow the oil to dry fully before using the wood surface. To apply linseed oil, clean the wood surface, apply the oil in thin coats, and allow it to dry completely between coats. You may need to apply multiple coats for a longer-lasting finish. Regular maintenance is recommended to ensure the wood remains safe for use.
Conclusion
Selecting the right food-safe wood finish from your grocery store can enhance the longevity and safety of your wooden kitchen tools. Whether you opt for mineral oil, coconut oil, olive oil, walnut oil, or a combination of oils with beeswax, proper application and regular maintenance are key to ensuring your wood surfaces remain free of contaminants and safe for food preparation.
